ABSTRACT:
A drive and steering apparatus for a vehicle of a type having ground engaging wheels or tracks on each side thereof. A shaft rotatably connected to the frame of the vehicle is selectively rotated by a motor through a drive train. A first drive assembly is rotatably disposed on one side of the shaft and a second drive assembly is rotatably disposed on the other side of the shaft. A first clutch mechanism is attached to the shaft and is selectively movable between positions in contact with the first drive assembly and out of contact with the first drive assembly. A first brake mechanism is attached to the frame and is selectively movable between positions in and out of contact with the first drive assembly. A first control mechanism is provided for simultaneously controlling the position of the first clutch mechanism and the first brake mechanism with respect to the first drive assembly, the first control means having a neutral position whereby the first clutch mechanism and the first brake mechanism are spaced from the first drive assembly, a driving position whereby the first clutch mechanism is in contact with the first drive assembly and the first brake mechanism is out of contact with the first drive assembly, and a braking position whereby the first clutch mechanism is out of contact with the first drive assembly and the first brake mechanism is in contact with the first drive assembly. The second drive assembly, second clutch mechanism, second brake mechanism, and second control mechanism operate substantially identically on the other side of the vehicle as the first drive assembly, first clutch mechanism, first brake mechanism and first control mechanism respectively, whereby the drive and steering of the vehicle can be controlled.
